(54) Chord presenting apparatus and method


(57) CPU (31) reads out plural chord data which are stored in external storage device (34) or the like and represent a series of chords, and presents to a user the chords represented by the chord data. In presenting the chords to the user, display (21) or external displayer (53) displays chord names along with a score or a lyric, or energizes key-press lamps (14) corresponding to the chord tones constituting the chords. External storage device (34) or the like is provided with a chord conversion table for converting hard-to-play chords to easy-to-play chords. In presenting the chords, CPU (31) presents the chords converted with the use of the chord conversion table. In this case, the hard-to-play chords may be controlled rank by rank or may be designated by the user. Thus, when chords are presented to a user, the user can perform chord playing smoothly at all times even if the user is a beginner player.
